Kevin Plank, Wilbur Ross & More: The 26 People Who Dropped Off The Forbes 400

Under Armour'sKevin Plank first hurtled onto the Forbes 400 in 2012, but lately the company has been hit by some of the same retail sector woes plaguing the rest of the industry. Worst still, in April the company posted its first quarterly loss since going public in 2005. All of this has helped push the sports apparel company’s stock down 60% in the last year and knocked $1.3 billion off its founder’s net worth. Plank is now worth $1.7 billion, $2.2 billion less than his peak in 2015. That would have been just enough to make the Forbes 400 ranks in 2016 but it wasn’t enough this year, as Plank dropped from the ranks along with 25 others.

With a minimum net worth of $2 billion, 18% higher than a year ago, it was tougher than ever to stay in the club. In fact, half of the 26 who fell off this year's list are as rich or richer than they were a year ago. The other 13, Plank among them, saw their net worths sink for various reasons.

Other notable dropoffs whose fortunes fell, despite strong markets, included Sears’ Eddie Lampert. His fortune dropped $600 million to $1.7 billion continuing a slide that started in 2014, a year after he took over as CEO.

Amid the country's ongoing opioid crisis, pharmaceuticals billionaire John Kapoor also lost his spot on the list this year. He stepped down as CEO of opioid maker Insys in January (while holding on to his majority stake in the firm). Insys has lost 36% of its value in a year as mounting federal and state investigations into the company's sales and marketing practices have hit the stock and Kapoor hard. Kapoor also holds a $930 million stake in generic drug manufacturer
Akorn Pharmaceuticals. That stock is up 16% in the last year.
